Eyes

The eyes are organs. They detect light, regulate the light through a diaphragm, focuses it through adjustable lenses and converts them into electo-chemical impulses in our neurons by photoreceptor cells called rods and cones. The image is converted into a set of electrical signals that are transmitted to the brain via neural pathways that connect the eye to the optic nerve and visual cortex of the brain. In short, eyes are very complex optical systems that convert light to distinguish objects and movement around us.

Myopia (Nearsightedness) occurs when the eye is too long in relation to it's focusing parts, or the cornea is to steep.

What causes myopia and hyperopia?

Nearsightedness and farsightedness are caused by light falling somewhere other than directly on the retina. Normally, light enters the eye through the lens and shines directly on the back of the eye called the retina. This is important because the retina is where all the receptors are, and they convert the light into nerve signals that are sent to the brain.

In nearsightedness, light comes through the eye and lands in front of the retina, causing images far away to appear blurred. This can be caused by a curvature in the cornea or lens that is misdirecting the light, or by the shape of the eye itself. If the eye is longer than normal, light may fall in front of the retina.

In farsightedness, light falls behind the retina, so that images close up appear blurred.This can also be caused either by the curvature of the lens or cornea, or by the shape of the eye. In the case of farsightedness, the eye may be shorter than normal.
